[security-observability] Daily Security Observability Report — 2026-06-10

[github-actions[bot]]

Executive Summary

The daily security observability report for June 10, 2026 shows a healthy firewall posture across 34 agentic workflow runs. Out of 1,548 network requests, only 3 (0.19%) were blocked — a significantly lower block rate compared to historical spikes seen on May 20 (22.3% block rate) and June 7 (24.0% block rate). The blocked domains — api.github.com, github.com, and proxy.golang.org — indicate two workflows are making direct GitHub API calls and one is attempting to fetch Go module proxies outside their firewall allowlists.

On the DIFC integrity-filtering front, no events were recorded in the last 7 days, indicating that all tool calls across all agentic workflows are flowing cleanly through the Data Integrity and Flow Control gateway without triggering integrity or secrecy policy blocks.

🔥 Firewall Analysis

Key Firewall Metrics

📈 Firewall Request Trends

The last 7-day window (June 4–10) shows a dramatically improved firewall posture compared to the historical spike on May 20, which recorded 735 blocked and 2,560 allowed requests. June 7 also saw elevated blocking (137 blocks). The current 7-day trend from June 8 onward shows near-zero block rates, indicating effective rule tuning has reduced false positives significantly.

Top Blocked Domains

Three domains were blocked today, each with a single blocked request. The api.github.com and github.com blocks in the "Daily Fact About gh-aw" workflow suggest it is using gh CLI or direct GitHub API calls that are not currently in its firewall allowlist. The proxy.golang.org block in "Delight" suggests a Go toolchain attempting to fetch module dependencies at runtime.

Most Frequently Blocked Domains

Domain	Times Blocked	Workflow	Category
api.github.com:443	1	Daily Fact About gh-aw	GitHub API
github.com:443	1	Daily Fact About gh-aw	GitHub Web
proxy.golang.org:443	1	Delight	Go Module Proxy

View Complete Blocked Domains List

All unique blocked domains (alphabetical):

• api.github.com:443
• github.com:443
• proxy.golang.org:443

🔒 Firewall Security Recommendations

1. Allow api.github.com:443 for "Daily Fact About gh-aw": This workflow is legitimately querying GitHub for repository facts. Add api.github.com and github.com to its firewall allowlist in the workflow configuration.

2. Allow proxy.golang.org:443 for "Delight": The Delight workflow appears to run Go toolchain operations at runtime. Allow proxy.golang.org and optionally sum.golang.org in its network policy to prevent build failures.

3. Historical spike investigation: The May 20 spike (735 blocked, 2,560 allowed) and June 7 spike (137 blocked, 435 allowed) represent significantly anomalous patterns. Audit those historical runs to determine if policy changes caused over-blocking or if new workflows were onboarded without proper allowlist rules.

4. Monitor o205451.ingest.us.sentry.io: At 525 requests (34% of all traffic), Sentry telemetry is the second-largest destination. Ensure this is expected and that no sensitive run metadata is being exfiltrated via error reports.

🔒 DIFC Integrity Analysis

Status: No DIFC Events in Last 7 Days

No DIFC integrity-filtered events were recorded in the last 7 days. All tool calls across all agentic workflow runs passed through the Data Integrity and Flow Control gateway without triggering integrity or secrecy policy filters.

This is a healthy signal — it indicates that:

• No workflows are attempting to pass untrusted (low-integrity) data to sensitive tools
• No secrecy policy violations were detected
• The DIFC policy configuration is not over-filtering legitimate tool calls

💡 DIFC Tuning Recommendations

1. Maintain current policy: The absence of filtered events with active workflows indicates the DIFC policy is well-calibrated. No immediate changes needed.
2. Baseline monitoring: Use this zero-event baseline to set alerting thresholds. Any future spike in DIFC events should be investigated promptly.
3. Re-evaluate after new workflow onboarding: When new workflows are added that interact with external data sources (issues, PRs, user input), verify DIFC policies cover their data flows before deployment.
